A nurse is providing teaching to a client following surgery to repair a detached retina of the left eye. Which of the following instructions should the nurse include in the teaching?

Choice A reason: Suctioning the ET removes secretions obstructing airflow, increasing peak airway pressure. Mucus buildup narrows the airway, triggering alarms. Clearing secretions restores patency, reduces pressure, and prevents complications like atelectasis or hypoxia, critical for effective ventilation in mechanically ventilated clients.
Choice B reason: Verifying ET placement ensures the tube is in the trachea. Misplacement, like esophageal intubation, increases airway resistance, elevating peak pressure. Confirmation via capnography or X-ray prevents hypoxia, ensuring proper ventilation and safety in clients on mechanical ventilators.
Choice C reason: Checking for kinks in ventilator tubing addresses mechanical obstructions raising peak airway pressure. Kinks restrict airflow, triggering alarms. Straightening tubing restores normal gas delivery, reducing resistance and maintaining effective ventilation, preventing hypoxia in mechanically ventilated clients.
Choice D reason: Administering a bronchodilator relieves bronchospasm, a common cause of high peak airway pressure. Bronchoconstriction narrows airways, increasing resistance. Bronchodilators relax smooth muscles, improving airflow and reducing pressure, addressing reversible causes like asthma in ventilated clients.
Choice E reason: Increasing tidal volume exacerbates high peak airway pressure, risking barotrauma or lung injury by forcing air against resistance. Addressing underlying causes like secretions or bronchospasm is safer, as higher volumes do not resolve the root issue, potentially worsening outcomes.

Choice A reason: Hypernatremia is unlikely with 0.45% sodium chloride, a hypotonic solution that dilutes serum sodium. Over-infusion risks hyponatremia, not high sodium levels. Monitoring for hypernatremia is inappropriate, as the solution’s low sodium content does not contribute to elevated sodium in fluid therapy.
Choice B reason: Assessing for fluid overload is essential, as 0.45% sodium chloride, being hypotonic, can cause water to shift into cells, risking pulmonary or cerebral edema. This is critical in clients with renal or cardiac issues, where monitoring for dyspnea or swelling ensures safe fluid administration.
Choice C reason: Hypoglycemia is not directly linked to 0.45% sodium chloride, which affects fluid and electrolytes, not glucose. Fluid shifts may indirectly stress metabolism, but hypoglycemia relates to fasting or insulin issues, making this an inappropriate focus for monitoring in this fluid therapy context.
Choice D reason: Dehydration is unlikely, as 0.45% sodium chloride provides free water, promoting hydration. It corrects hypernatremia or replaces fluid losses. Evaluating for dehydration is unnecessary unless infusion is inadequate or losses persist, which is not indicated in the context of this hypotonic solution.
